1.
Position heater element section over the blower

blower cut-off scroll. Heater should be rotated
180 degrees if necessary to align. This ensures
proper blower discharge of air over the heater
elements.

2.
Attach electric heat plenum to unit using #6 or larger
sheet metal screws.
Note: Ensure plenum is securely attached to
HAB unit only and not to blower housing
extension.
Ensure duct materials are compatible for 250º F
operation. Refer to NFPA pamphlet
90A and 90B for
more information.
Ensure ample room exists in the ductwork. Electric
heater must have at least 24 inches of straight duct
clearance before an elbow. If 24 inches are
unavailable, devices such as turning vanes or baffles
may be required.
Note: Electric heaters are incompatible with
discharge equipment.

Add insulation, if necessary, to outside of heater
plenum section.
